I suppose that wishing this was an alignment issue was somewhat foolish. :roll eyes:
I've had the most success clearing clogged nozzles in the past by using the ol' unplug the printer and pull the printhead over a lint free cloth saturated in gentle surfactant method. I'll usually do a cursory clean of the wiper blade and pump & cap assembly at this point as well.
I've had the most success going straight to performing a single power clean at this point. (I feel that the nature of this clean might be better suited for pulling any dried pigment that may have been culprit?) Then, after a nozzle check, I'll print from an ink separation file until all's flowing well again. This has always done the trick up until now.
My concern still lies with those vertical straying lines because of their alignment to the missing section. This may directly correspond to whatever problem is causing dropout only, I've never seen missing nozzles cause anything like this before. Moreover, these errant vertical lines don't seem to be affected by the cleanings. They look identical in each nozzle check as far as I can tell.
Should I attempt a more aggressive cleaning?
Your assistance is very much appreciated Kelly.
